Arizona upstarts Spafford are still busting out of their shell as of late. With two highly anticipated post-Phish late night shows this New Year’s Eve, and a slate of 2017 tour dates supporting like-minded jammers Umphrey’s McGee on deck, there’s a lot to be excited about with these rising stars of the improv scene.

Back in September, Spafford hit Boulder, Colorado’s Fox Theatre as part of their Breakout Tour. The band showcased their unique and aggressive jamming on that evening, infusing progressive rock, speed-funk, and jazz-fusion to create an awesome vibe that left the crowd begging for more.

Thankfully, the band has released pro-shot footage of one of the highlights from their set at the Fox. Below, you can watch the raging version of “Electric Taco Stand” that they delivered at the Fox, and experience the glory of Spafford for yourself.

If you enjoyed the video above, make sure to check out Spafford at their post-Phish late-night shows this December. The band will be sharing the bill with the Magic Beans on December 30th or on December 31st at American Beauty, just one block from Madison Square Garden.
